.TransiEnt.Consumer.Heat.ThermalHeatConsumer_L3.Base.SolarRadiation

Information

1. Purpose of model

Calculation of heat flow rates to building due to solar radiation

2. Level of detail, physical effects considered, and physical insight

Calculation of direct irradiation to walls with 4 instances of TransiEnt.Producer.Heat.SolarThermal.Base.IrradianceOnATiltedSurface (one for each direction).

Calculation of transmittance for windows of each direction.

Calculation of homogenous distribution of diffuse irradiation on all surfaces considered.

It is assumed that 50 % of the direct irradiation is absorbed by the floor and the rest distributed evenly to the other surfaces.

Calculation of absorbed heat by windows.

3. Limits of validity

4. Interfaces

Heat Ports to window and surrounding surfaces

5. Nomenclature

7. Remarks for Usage

To be used in ThermalHeatConsumer_L3

8. Validation
